you can see how thick those walls are, triple clay brick or more, but that's about as tall as they could build before reinforced concrete. These are just like the collapsed Balfour bldg on KW. The exterior walls were load bearing. Unless you added flying buttresses *reserved exclusively for churches and cathedrals* you couldn't go much higher or the exterior walls would collapse from the weight. Unless you built a pyramid but .... whatever...
Lister on the other hand was the next generation in building technology. A interior grid of re-enforced concrete pillars. The exterior walls could be anything light weight because the floor plates are cantilevered off the interior grid of pillars. Now it's usually a glass curtain. but then it was a brick and stone curtain with embellishments. That also marked the beginning of the SKYSCRAPER.
